我正在使用mule 3.2.0和 我在java-class中调用muleclient.send方法,它将soap-request发送到mule流(此处不存在),将其发送到接收请求的http端点,使用代理模式将其记录到我的数据库并将其传播到“ServiceFlow”,它具有Dispatcher转换器 - java类,它使用MuleClient.send(String url,Object payload,Map messageProperties)方法的调用将有效负载数组的一个对象分派给端点。 然后它由cxf:jax-ws-client处理,再次登录到db并转移到另一个Dispatcher实例(其中传入的有效负载的类型为Object [])。我有http端点进行服务调用。这部分工作正常。 但是在收到回复时会出现麻烦。我已经把Test1(2,3,4)变换器打印到我的流中的调用链(它们只是执行System.out.println()),并看到它们以一个奇怪的顺序被调用:我有它像1,3然后TestTransformer(也是sysouter)然后我在主流“服务流程”的调用者中得到错误“NullPayload”,然后我收到测试4和测试2出局。忽略模式“1Proxy”中的responseTransformer-refs,如“ServiceProxy”中所示。我一直在寻找一周的解决方案,但找不到它。在调试中,我可以看到名为“TestTransformer”的变换器具有预期的有效载荷(Object []),但是当我在类调用者中收到它时,它显示为“NullPayload”。我现在可以看到我的一个端点有路径元素而不是ref,不确定这是否会对流产生任何影响,但会检查它。还尝试使用“响应”块来确保我的流程按预期运行。任何建议赞赏。感谢
以下是我的配置:

答案 0 :(得分:1)
好吧,我的问题确实是“path”元素,而不是引用现有的带有“ref”元素的vm端点,如
<inbound-endpoint ref="vm1Out"/>
